Description

Verfahren zur Herstellung von Kakaopulver Zusatz zum Patent 83,1799 Um Kakaopulver herzustellen, hat man bisher den Rohkakao, nachdem er gegebenenfalls einem Fermentationsprozeß unterworfen worden war, zuerst geröstet, dann entfettet und den erhaltenen Kakaopreßkuchen zerkleinert. In dem Bestreben, dem so erhaltenen Kakaopulver einen Löslichkeitsgrad zu geben, wurden bei dieser Behandlung auch Alkali, Pottasche, Kalk, Soda, Natron u. a, zugesetzt. Eine echte Löslichkeit der einzelnen Kakaokernteilchen wurde aber auch hierdurch nicht erzielt. Man kann dabei höchstens von einer guten oder schlechten Schwebefähigkeit sprechen. Die einzelnen Teilchen wurden bei dieser bekannten Behandlung nie kleiner als 40 Mikron. Um aber zu einer kolloidalen Lösung zu kommen, ist eine Zerkleinerung auf mindestens io Mikron und darunter erforderlich. Es wurde gefunden, daß man einen solchen Feinheitsgrad erhalten kann, wenn man die rohen Kakaobohnen zunächst nach dem Verfahren des Hauptpatents behandelt, nämlich in Wasser oder einem wäßrigen Alkohol-Essigsäure-Gemisch einem erhöhten Druck und anschließend einem Unterdruck aussetzt, und dann die entschälten Bohnen in noch feuchtem Zustand in einer Kolloidmühle zerkleinert. Es hat sich überraschenderweise gezeigt, daß die Verbindung dieser beiden Behandlungsmethoden die eben erwähnte weitgehende kolloidale Zerkleinerung ermöglicht, was bei den bisher üblichen Verfahren nicht möglich ist.Process for the production of cocoa powder Addition to patent 83.1799 In order to produce cocoa powder, the raw cocoa, after possibly having been subjected to a fermentation process, has hitherto been first roasted, then defatted and the cocoa press cake obtained has been crushed. In an effort to impart a degree of solubility to the cocoa powder thus obtained, alkali, potash, lime, soda, soda and the like were also added in this treatment. A real solubility of the individual cocoa core particles was not achieved by this either. At most one can speak of a good or bad ability to float. The individual particles never became smaller than 40 microns in this known treatment. In order to arrive at a colloidal solution, however, it must be reduced to a size of at least 10 microns and below. It has been found that such a degree of fineness can be obtained if the raw cocoa beans are first treated according to the process of the main patent, namely in water or an aqueous alcohol-acetic acid mixture to increased pressure and then subjected to negative pressure, and then the peeled beans Crushed in a colloid mill while still moist. Surprisingly, it has been shown that the combination of these two treatment methods enables the above-mentioned extensive colloidal comminution, which is not possible with the methods customary up to now.

Es ist bekannt, geröstete oder nicht geröstete Kakaobohnen in Vibrationskolloidmühlen bis zum flüssigen Zustand zu vermahlen, wobei auch vorgeschlagen wurde, eine in.der Kälte sich verfestigende Zuckerlösung hinzuzufügen. Des weiteren ist bekannt, zur Herstellung von Schäkolade die trockenen Kakaobestandteile zu pulverisieren und (hierbei eine Kolloidmühle zu verwenden. Dabei soll aber der Feuchtigkeitsgehalt der Masse 3% nicht überschreiten.It is known to use roasted or unroasted cocoa beans in vibratory colloid mills Grind to a liquid state, which is also suggested became, add a sugar solution that solidifies in the cold. Furthermore is known to pulverize the dry cocoa ingredients for the production of Schäkolade and (use a colloid mill for this. However, the moisture content should be of the mass do not exceed 3%.

Im Gegensatz zu diesen bekannten Methoden wird gemäß der Erfindung auf einen höheren Feuchtigkeits-, d. h. Wassergehalt Wert gelegt. Die Kakaobohnen werden in der Kolloidmühle in dem Zustand vermahlten, in weldhem sie .die Behandlungsstufe verlassen. Hierbei wird von Rohkakaobohnen ausgegangen, die bekanntlich einen Wassergehalt von 55% haben. Da diese Bohnen in der Vorbehandlungsstufe in Gegenwart von Wasser behandelt werden, weisen sie also in der zweiten Stufe, d. h. der Zerkleinerungsstufe, einen Feuchtigkeitsgehalt auf, der mindestens so groß ist wie der der Roh-Bohnen.In contrast to these known methods, according to the invention to a higher moisture, d. H. Water content is important. The cocoa beans are ground in the colloid mill in the state in which they .the treatment stage leaving. This is based on raw cocoa beans, which are known to have a water content of 55% have. Because these beans in the pretreatment stage in the presence of water are treated, they show in the second stage, i.e. H. the shredding level, a moisture content that is at least as great as that of the raw beans.

Der gewünschte Anteil an Fett kann aus dieser zerkleinerten Masse durch Zentrifugieren abgetrennt werden. Die entfettete Masse wird daraufhin in an sich bekannter Weise im Vakuum getrocknet und geröstet, wobei es zweckmäßig ist, den Trocknungs-und Röstvorgang mit Hilfe von Hochfrequenzstrahlen durchzuführen. Statt dessen ist auch die Wärmebehandlung mit Infrarot- oder Ultraviolettstrahlen möglich. Es hü sich gezeigt, daß die Zuhilfenahme von Hochfrequenzstrahlen die Verwendung der üblichen Brecher und Schlagkreuzmühlen unnötig macht, daß vielmehr der nach der Entfettung verbliebene Kakaokuchen auf diesem Wege in seine kleinsten Teilehen entfällt.The desired percentage of fat can be obtained from this crushed mass separated by centrifugation. The defatted mass is then in an is dried and roasted in a known manner in a vacuum, whereby it is expedient carry out the drying and roasting process with the help of high-frequency jets. Instead, heat treatment with infrared or ultraviolet rays is also possible possible. It has been shown that the use of high frequency rays is beneficial the usual crusher and cross beater mills makes it unnecessary that rather the one after The cocoa cake remaining after the degreasing is broken down into its smallest parts in this way not applicable.
